How does math relate to electrons and ion formation?

2 answers:

In order to find the NET nuclear charge from an atom's valence electron to the proton nucleus, you need to do some simple math in order to find the charge.

You would also need to apply math when you need to figure out what the charge on an ion is by either adding or taking away electrons depending on whether it is an anion or cation.

Answer and explanation;

Ions are formed when an atom looses or gains electrons.

-Ionic charges are created when there is an imbalance of protons and electrons on an atom. Since we can not change the number of protons on the nucleus of an atom, a positively charged ion will be created when there are fewer electrons than protons (in other words when an atom looses electron). A negatively charged ion is formed or created when there are more electrons than protons in an atom (when an atom gains electrons).

-When electron are added, you are adding more negative charge and thus, results in the creation of a negative ion (anion), and when electrons are being lost by an atom, one is removing negative charge, resulting in creation of a positive ion (cation).

How many moles of hydrogen gas will be produced when 12 g of Mg will react completely with excess of an acid according to the fo

lina2011 [118]

Answer:

0.49 mol

Explanation:

Step 1: Write the balanced equation

Mg + 2 HCI ⇒ MgCl₂ + H₂

Step 2: Calculate the moles corresponding to 12 g of Mg

The molar mass of Mg is 24.31 g/mol.

$12g \times \frac{1mol}{24.31g} = 0.49mol$

Step 3: Calculate the moles of H₂ produced by 0.49 moles of Mg

The molar ratio of Mg to H₂ is 1:1. The moles of H₂ produced are 1/1 × 0.49 mol = 0.49 mol.

Which form of bonding has unequal sharing of electrons between two elements?

Vlad1618 [11]

Hello!

Your answer would be polar covalent.

Covalent bonds are where two atoms come together, and share electrons between each other, and are therefore, bonded.

In some cases of molecules that are bonded with a covalent bond, one of the atoms is more, you could call it selfish, and takes more of the electrons. A prime example of this is H20, or water. One of the atoms takes the electrons for longer, and therefore has a more negative charge because electrons are counted as negative charges.

This bond where an atom "hogs" electrons, is called a polar covalent bond, respective to the changing charges for the atoms.

So your answer is d.

Hope this helped!

When energy is transferred from the air to the water, what happens to most of the energy? A. It travels through the water. B. It

BigorU [14]

Answer: Option (A) is the correct answer.

Explanation:

When energy is transferred from the air to the water then energy is absorbed by the water molecules.

This energy travels through one molecule of water to another molecule of water by the process of convection.

Thus, we can conclude that when energy is transferred from the air to the water, then it travels through the water.
